Note:1.To ensure flowmeter working stability, it should be assured that the working pressure is not less than double of max loss of pressure when the flowmeter used to measure liquid; when you measure medium is air, it should be assured that the working pressure is not less than five times max loss of pressure:2.Above measuring range is for reference only, you can select other measuring ranges according to range ratio 10:1:3.Flowmeler can be specially made for you as per medium density viscosity, temperature pressure and other parameters you supply.
